The aim of this unit is to introduce learners to the basic hardware and software components that make up
computer systems and for learners to carry out basic installation and configuration.

Most learners will set up a computer system at some stage, which may belong to them or someone else
and it may be a desktop, laptop, PDA or games console. To do this, learners need to know about the
different elements of a computer system and how hardware works with software and how all the elements
communicate to make the system function.
